The characteristics of an atom
By: Kevin J. Putnam
The characteristics of an atom is pretty simple, once a handle on the size of the atom is in perspective. The size is small, so small that the human mind can not get a visualize of it, we can "see" it mathematically or through an...
How to make ethanol
By: John Traveler
Ethanol is an alcohol that has the formula C2H5OH. Its' basic constituent is the Ethylene molecule (C2H6), and Ethanol is produced through a process known as hydration synthesis or can be accomplished with fermentation.ETHANOL PRODUCTION WITH HYDRATION SYNTHESIS:Ethylene is a relatively common compound. It...
What DNA stands for
By: John Traveler
The acronym "DNA," stands for "Deoxyribose Neucleic Acid." If you are a chemist, biologist or associated with some other scientific discipline which deals with such terminology, then you know exactly what I am talking about when I make reference to this chemical composition...
An overview about the chemical element Copper
By: Melanie Grimes
Copper, known as cuprum was named after the island of Cyprus, where it has been mined since ancient times. Copper and gold are the two most ancient metals known to man. They are unique in that both of them are the only the only colored...
